bootstraping never ends

[hiletmis]

I have set an avalanche node a while ago. It started fetching X and P chains and fetched them successfully. So far it was so good. But when it comes to bootstrapping C chain, the node started acting strange. It has been over a week and still not completed.

I thought if there is a problem and restarted the node but that didn't help the ETA increased on every restart though.

Bootstrapped 8M block in 2 days but I'm waiting for the last 5M blocks for days!

I am getting this log and progress to slow. Apr 12 05:43:03 magna avalanchego[33284]: INFO [04-12|05:43:03.253] <C Chain> snow/engine/common/queue/jobs.go#173: executed 260000 of 4731899 operations. ETA = 393h41m9s

Operating System Ubuntu 20

Additional context The node is running on cloud. The machine has a decent configuration.

I have started a mainnet node about a week ago and it also have not been bootstrapped till now. My system specifications are also good(EC2 instance :- t3.2xlarge with 32 GB ram). Can someone help on how can i reduce this time ?

[hiletmis]

No one can reduce the sync time ATM. 512 SSD is also not enough fyi

Running into a similar issue with an already partially synced node:

783hrs to catchup 340k blocks?!

Meet the same problem. Any one can help or just give us a snapshot.

In our case, it was caused by bad IO performance on a ZFS volume nearing full capacity.

[DaMandal0rian]

This is usually an IO and/or CPU issue with not enough cores. Fast disk hardware (SSD,nvme) and high IOPS is essential. Could be poor bandwidth too.

@xinxurockx let me know if you need a snapshot.

[singhsahilzeeve]

Does passing --state-sync-enabled=true allows C chain to bootstrap faster ? If after bootstrapping will it download previous blocks (historical data ) also ?

[fatminer]

i have the same problem.

After 10 days, the C-Chain synchronization has not finished.

Isn't there an option like fast-sync like go-ethereum?

Can you provide me a snapshot?
